description

The HR150 Series™ DC/DC converters have been designed to give

industrial applications the same high reliability, small size, and high

performance that Interpoint has provided to military and aerospace

programs since 1969.

models and 250 kHz typical for triple output models. They achieve

high isolation (500 V, 100 megohm) through use of a transformer in

the forward power circuit and an opto-coupler in the feedback control

loop.

HR 150 Series input ranges are 10 to 16 VDC or 18 to 36 VDC.

Outputs are available as 5, 12, 15, ±12, ±15, +5 & ±12, and +5 & ±15

VDC. The converters typically provide greater than 80% efficiency

over the entire input range and from 25% to full load. Line regulation

is typically within 0.1 % and load regulation within 0.2%.

HR150 converters are designed to operate between –40°C and +85°C

case and are short circuit protected up to a case temperature of 85°C.

The combination of high conversion efficiency and heat dissipating

metal enclosures minimizes heat sinking requirements. If additional

dissipation is desired, heat conducting material (PCB, copper sheet,

heat sink, etc.) may be brought into contact with the unit’s baseplate.

An inhibit function is provided for HR150 converters when the inhibit

input pin is connected to the input common. The open circuit voltage

of the inhibit input pin is 8 to 10 VDC (Vin = 12) or 11 to 13 VDC (Vin

= 28). The inhibit input pin must sink approximately 1 mA during the

inhibit state. During inhibit, the converter’s output voltage drops to less

than 1 volt and the input current is typically 8 mA.

eliability

Each HR150 converter is built to perform reliably in the harshest

environments. Assembled using thick-film hybrid technology, HR150

converters have more uniform thermal coefficients and 50% fewer

connections than converters built by surface mount techniques. The

HR150 converter parts use the same manufacturing procedures and

quality controls that we apply to converters designed for commercial

airliners, the space shuttle, advanced fighter aircraft, and other high

reliability applications. The steel cases are hermetically sealed in a dry

nitrogen environment and are guaranteed a maximum leak rate of less

than 10-3 atm-cc/sec. All devices are 100% electrically tested.

The HR150 Series manufacturing techniques provide extremely small

size and low profile components. Each converter uses less than 2.7

square inches of board area. The overall power density is from 11 to

17 watts per cubic inch.

The HR150 Series converters are high efficiency, low noise, pulse

width modulated, forward mode switching regulators with a constant

switching frequency of 125 kHz typical for single and dual output
